UNITED STE RAY R. RAYMOND, OF NEW YORK, N.

LOCK.

Application fi led May 8,

To all whom it may concern.

Be it known that RAY R. RAYMOND, a citizenof the United States, and resident of the city of New York, borough of Manhattan, county of New York, and State of New York, have invented a new and Improved Lock, of which the following is a full, clear, and exact description.

My invention relates to a lock, and aims to provide a device of this character, which is particularly adapted for use in connection with a telephone instrument although it is not necessarily limited to this application. 7

In connection with telephone instruments, it is a Well appreciated fact that considerable diificulty has been experienced withthe same, incident to their unauthorized use. Thus a subscriber will be presented with a bill by the telephone company for charges which have not been incurred by his use of the instrument, although unauthorized persons have called for and received the desired numbers during the absence of the subscriber.

Thus my invention is primarily adapted for use in connection with a lock which may readily be'applied to a telephone instrument or detached therefrom, and which when in applied position will absolutely preclude any danger of the instrument being used, thus overcoming the difficulty aforementioned.

It is a further object of the present invention to provide a device of the character stated which when placed in association with a telephone instrument will not cause any damage to the same.

A still further object of the invention is that of providing a lock which will embody an extremely simple construction, and which will at all times be positive in operation.

With these and further objects in mind the present invention consists of a lock presenting a body portion which is adapted to be associated with certain of the moving parts of a telephone instrument, to prevent the movement of these parts, and to thus prevent a person from using the instru ment.

Reference is had to the attached sheet of drawings which illustrates one practical embodiment of my invention, and in which it will be seen that;

telephone instrument and showing certain portions of the same broken away,my improved type of lock being associaated with the parts of this instrument, and

Figure 2 is a side elevation of the body I of the lock.

In the embodiment illustrated" I have shown my lock associated with a telephone instrument, for which purpose it is primarily intended, but I wish it understood that the same might be utilizedin other connections without departing from the spirit of my invention. I

Thus in these drawings the reference numeral 5 indicates the pedestal of a telephone instrument, which movably carriesa receiver hook 6, the latter in turn supporting the receiver 7 in the usual manner. As in instruments of this type it will be understood that a spring (not shown) is pro vided for forcing the hook 6 "upwardly but the weight of the receiver 7 is such that the hook will normally be retained in lowered position, at which point connection will not be established either through the transmitter or receiver. However it is well understood that the opening within the pedestal 5 through which the body of thevhook 6 extends is sufficiently large to allow the hook to move upwardly when the receiver is removed from the hook, and the ends of this hook terminate also as in customary construction, in a loop 8. Now referring to the construction of my lock it will be seen that the same embraces a bodyor shank-9 which is formed of metal, and has one of its ends preferably squared and tapered .as at 10 its opposite end terminating in aloop 11. Now upon the subscriber of a telephone desiring to prevent any unauthorized usage of the instrument, the receiver is applied to the hook 6 in the usual'manner, causing the latter to move downwardly to the position shown in Figure 1 thus breaking all speaking connections. WVhen the parts are in this position the end 10 of the lock body 9 is inserted into the opening now presented between the upper edge of the hook 6 and the body of the pedestal 5, and this end is introduced until the loop 11 of the body 9 aligns with one of the loops 8 of the hook 6. e

When the parts are in this position it will be found that the hook 6 cannot be moved to a suflicient extent with respect to the pedestal 5 to permit of a speaking connection being established, and thus a lock 12 of any desirable type may he inserted through the aligned loops 11 and 8, and a subscriber may teel perfectly at ease to leave the instrument Without any danger of the same being used by an unauthorized person. n

Thus all of the objects of this invention have been accomplished and it Will further be appreciated that numerous modifications of structure might readily be resorted to without in the least departing from the scope of my claim; which is:

In a lock for telephone rewivers including aremovable structure having one end for impermanent accommodation Within the pedestal opening from which the receiver hook emerges and the opposite end of the structure presenting an eye formation to be locked to a terminal eye portion of the receiver hook a structure for such purpose comprising a rigid member formed of a single piece of Wire including merely a straight length and an eye formed at one end or said straight length by bending the Wire piece, all portions of the Wire piece'heing' in one plane.
